If there’s anything the Kardashian-Jenner family isn’t, it’s quiet.

The five sisters — Kourtney, Kim, Khloé, Kendall, and Kylie — are never ones to sit in the background when something is happening around them, especially when it’s something they disagree with.

Just this week, Kendall Jenner hit back after bullies attacked her online for having acne at the Golden Globe Awards.

Now, it’s big sister Kim’s turn to slam the haters. And this time, it’s about something near and dear to all the sisters: their mom, Kris Jenner. Kris is not just their mom, she’s also their manager (or “momager”) and their biggest supporter.

Kim came across a tweet claiming that her mom used to be “chubby-faced” when she modeled as a 22-year-old. Kim was outraged that they were body-shaming Kris by calling her chubby, so she fired back with a tweet of her own.
